20-year old Shanghai Shenhua defender Yang Yun is on trial with Italian giants Juventus.

The Bianconeri saw Yun when the club was on a tour of Asia last summer and were impressed by him.

"He is not very well known even in China," Oberto Petricca, his agent, admitted.

"I have only seen him play a couple of games.

"This operation began with the tour Juventus went on last year," Petricca explained.

"Yun is not only valuable in a technical sense, I believe he represents the general synergy between the Bianconeri and Shanghai Shenhua."
